This is our second summer with a pool, and I am finally starting to understand how it all works. I finally got a 6-way test kit (not the one recommended on here), and my chemicals are out of control! I have been fighting a slightly cloudy pool, with occasional scaly spots that sometimes turn into what looks like brown algae (but quickly clears up with a shock of 8 gallons of chlorine). And it won't hold chlorine; but for the most part the pool is clean and clear. My question is, can I just keep up what I'm doing (spending a lot on chlorine), and start fresh next year with a drain and refill? We live in MI, so our swimming season only has about a month and a half left. Here is the good, bad and ugly:
23,000 gallon inground vinyl liner pool, with a 1.5 hp sand filter that we run 24 hrs. a day.
As of tonight:
FC: 0 (I added a gallon of sanitizer last night, and it read 2-4 ppm this morning prior to rain and 5 kids swimming)
Total Alkalinity: 200 ppm
Hardness: 500 ppm
CYA: too high to measure with kit that goes up to 100
I feel like there is nothing I can do to save it at this point, but wait and start fresh. Is that my best course of action? Also, can someone please direct me to a thread to help me better understand how to run/maintain my filter? Getting a better handle on that is my next bit of homework
